What is a pulmonary contusion?
Syndrome following blunt chest trauma of CP + resp difficulty w/ confirmation on imaging
Sx of pulmonary contusion
Usually within hours of injury, peak at 72hrs, resolves within 1 wk
SOB, CP, hemoptysis
Physical for pulmonary contusion
Serial vitals
Palpable + pleuritic CP
Auscultation usually normal (consider hemothorax if lung sounds abnormal)
Inspect naso-oro-pharynx for bleeding
Clear C spine
Abdo exam
CXR findings for pulmonary contusion
peripheral infiltrate in area of trauma when significant contusion occurs:
Generally seen within 6 hr but may take up to 48 hr for radiographic changes
The infiltrate may not correlate to lobular architecture.
DDx for pulmonary contusion
Pulmonary emboli
Traumatic pneumothorax or hemothorax
Diaphragmatic, splenic, or hepatic injury
Pulmonary laceration or hematoma
Spontaneous pneumothorax
Rib fracture or contusion
Naso-oropharyngeal trauma
Management of pulmonary contusion
ABCs
C spine
Transport if SOB
O2
Condition self resolves, rest from strenuous exercise
RTP: 1-2 wks if no SOB or hemptysis
Complications of pulmonary contusion
Posttraumatic empyema
ARDS
Pneumonia
Prevention of pulmonary contusion
Protective equipment + padding
Seat restraints in motor sports
RF for pulmonary contusion
Collision/contact sports
Sports with high speeds or where the athlete is airborne:
Cycling, equestrian, winter sports, auto and motorcycle racing, extreme sports, and so forth
Sx of splenic trauma
LUQ pain, left shoulder pain
Physical for splenic trauma
vitals, postural vitals
Auscultate + palpate abdo
Cullen sign - discoloration of periumbilical area (sign of intra-abdominal bleeding)
Turner sign - discoloration of flank (sign of intra-abdominal bleeding)
Spleen exam:
Place the patient in the right lateral decubitus position, permitting gravity to anteriorly displace the spleen.
Ensure that the patient’s hips and knees are flexed to relax the abdominal muscles.
Proceed with gentle palpation during deep inspiration.
Palpation of the spleen over 2 cm below the left costal margin is an abnormal finding in adults.
Ix for splenic trauma
CBC, lytes, type + crossmatch, serial Hb
Thoracic + pelvic XR
CT abdo pelvis if stable
If unstable, FAST
DDx for splenic trauma
Rib fracture
Diaphragmatic injury
Thoracic aorta rupture
Peritonitis due to liver injury or ruptured hollow viscus
Rectus sheath hematoma
Spontaneous splenic rupture secondary to splenomegaly associated with infectious mononucleosis
Splenomegaly with rupture secondary to:
Congestion: liver disease
Infiltration: amyloidosis; hematologic malignancies such as leukemia, lymphoma, myeloproliferative disorder
Inflammation: acute or chronic such as HIV, tuberculosis, parasitic diseases
Extramedullary hematopoiesis
Management inc RTP of splenic trauma
Conservative (monitoring) vs surgical
If splenectomy, imms administered 2 wks post op
Consider abx prophylaxis
RTP - 8-10 wks
Complications of splenic trauma
Delayed rupture
Splenic pseudocyst
Overwhelming postsplenectomy infection
MOI + sx of renal trauma
MOI
Usually direct impact to abdo or flank, blow to back, fall from height or rapid deceleration
Hx - Gross hematuria
Physical for renal trauma
Vitals
Abdo exam
Ix for renal trauma
CBC, Cr, eGFR
UA
CT abdo pelvis
DDx for hematuria
Glomerular disease (post infectious, SLE, vasculitis, HUS, TTP, Alport’s syndrome, meds)
Hydronephrosis
Polycystic kidney disease
Trauma
Urethral stricture
Urogenital stones
Urogenital neoplasms
Hematologic disorders (e.g., sickle cell disease or trait, Renal artery thrombus, coagulopathies)
Connective tissue disease, inflammation
Infection (UTI, pyelonephritis)
Pregnancy
BPH
NSAIDS/Ibuprofen especially with dehydration
Pseudohematuria due to drugs (Levodopa, Nitrofurantoin, Rifampin, Septra), vegetable dyes, beets, berries
Management of renal trauma
Conservative - monitoring, bed rest til hematuria resolves
Surgery if hemodynamically unstable
Complications of renal trauma
The leading complication is extravasation of urine and infection of this urinoma
Early (acute, <1 mo):
worsening flank pain, uncontrolled bleeding, abdominal distention
Late:
Page kidney phenomenon/arterial hypertension (up to 40% of cases): extrinsic compression of renal parenchyma leading to intrarenal ischemia and activation of the renin-angiotensin system
Hypertension and renal impairment develop and can occur in native kidneys and renal allografts.
Hydronephrosis, stones, chronic pyelonephritis
Causes of hematuria in sport
Exercise induced hematuria
Trauma
Hypoxic damage to nephron
Hx + sx for hematuria
EIH is most pronounced on first void
Relation of hematuria to stream (beginning, throughout, at end)
Flank trauma or pain, frequency, urgency, nocturia, dysuria
Prior stones, UTI, vaginal or penile discharge, sexual activity, relation to menstruation
Recent sore throat
Fever, rashes, wt loss
Physical for hematuria
Usually normal exam for EIH
Vitals
Abdo + flank exam
Genitourinary exam
